雄安新区D16地热勘探井分层抽水实践

Layering pumping practice of D16 geothermal exploration well in Xiong’an New Area

雄安新区地热勘探D16井针对雾迷山组和高于庄组2个热储层在确保钻井施工井内安全的前提下,实施分层抽水试验,首次获得了2个深部基岩热储层的水文地质试验成果。为后续雄安新区地热勘探井钻井施工和水文地质勘查探索了基本技术程序,制定了工作样板,对雄安新区规范实施地热勘探具有重要意义。

Layering pumping tests were carried out for the two thermal reservoirs of Wumishan and Gaozhuang Formation under the premise of drilling safety,and the hydrogeological test results of two deep hot bedrock reservoirs were obtained for the first time.The basic technical procedures were explored for the subsequent drilling construction of geothermal exploration wells and hydrogeological exploration in Xiong’an New Area,and the work model was formulated,which is of great significance for the standardized implementation of geothermal exploration in Xiong’an New Area.
